This topic describes how to replace the disk drive for
the SAN
Volume Controller 2145-4F2 node.
Attention: - Handle the disk drive with care and keep it away from strong magnetic
fields.
- The disk drive is electrostatic-discharge (ESD) sensitive. Take
precautions to avoid damage from static electricity. Wear an anti-static
wrist strap and use a static-protected mat or surface. For more information,
see Handling static-sensitive devices.
To replace the disk drive and cables, perform the following
steps:
- Check whether the old disk drive has any jumpers installed.
If it does, install matching jumpers onto the new disk drive. Figure 1 shows
the location of the jumpers.

- Find the rails and screws that are shipped with the new
disk drive and attach the rails to the disk drive, as shown in Figure 2.

- Push the disk drive forward and into the SAN
Volume Controller 2145-4F2.
Note: When you install the disk drive, push it into the SAN
Volume Controller 2145-4F2 until
the latches click into place.
- Restore the front panel.
- Connect the SCSI signal connector
and the power connector 
, which
are shown in Figure 3,
to the back of the disk drive. Figure 3. SAN

- Replace
the top cover. See Replacing the top cover.
- Place the node in the
rack. See Replacing the SAN Volume Controller in a rack.
- Reconnect the
power cords and the fibre-channel and Ethernet cables. Ensure that
you replace the fibre-channel and Ethernet cables in the same ports
from which they were removed.
- Turn on the node. When you turn on the node, use the node rescue procedure
to install the SAN Volume Controller software
on the new disk. Then add the node back into the cluster. See Performing the node rescue.
